This unit is harder than it looks, very challenging. The idea is to jump from one end to the other, but their is a catch! You have to stay on top of each red ball without falling off, jumping from one to the next. if you fail their is soft landing to catch your fall.
If you are taking measurements for a structure such as a building or fence, please provide the height of the structure here. If height does not apply to the wash, for instance for a gutter wash, leave this field empty. Please note if you enter a value here after taking measurements, you will need to take measurements again.
